Hey ned, I was in yesterday and bought some live rock. I was ecstatic to find a small tubeworm and some type of bivalve (maybe a scallop?) But then last night I saw a bristleworm ( I'm not grossed out easily, but this thing somehow did it for me) It was around 5-6" and pink, with white bristles. Any way I can capture it and either kill it, or are they useful?
